Naaptol has worse products not worth for the money we spent . Instead opt for flipkart or amazon the same product you find two times less than naaptol product price.I bought 5mins exercise roller(as product mentioned it works only 5mins, disposable product.) the quality is poor.Now they are not ready to refund me, the service sucks.
Note: If any one is giving good reviews about naaptol then it is 100% Naaptol seller.(without rating I couldn't post so don't consider my rating they don't deserve a single star)
